Experimental training board has been designed specifically for the study of frequency modulation and demodulation. Practical experience on this board carries great educative value for science and engineering students.Object:
- To observe the effect of D.C. voltage on frequency of carrier waveform
- To frequency modulate the carrier with Audio signal, observe F.M. waveform on C.R.O., and measure its modulation index
- To demodulate the F.M. singal and observe the output on C.R.O.
- To plot the characteristics curve of the slope detector demodulating circuit
Features:
The board consists of the following built in parts:
- ± 12V D.C. at 100 mA, IC Regulated Power Supply
- Carrier generator circuit which generates the carrier signal
